Abstract
Statins play an important role in the treatment of hyperlipidemia, but drug resistance and adverse effects greatly limits their application. To discover new lipid-lowering drugs, three different series of tetrahydroprotoberberine derivatives (THPBs) were designed and synthesized. These compounds were first tested for their effects on viability of HepG2 cells and 21 compounds with the percent of cell viability over 90% were further screened to evaluate their ability to reduce total cholesterol (TC) and triglyceride (TG) levels. Among these derivatives, two compounds displayed significant down-regulation both intracellular of TC and TG content, especially compound 49 exhibited the greatest efficacy. Mechanistically, compound 49 promoted proteasomal degradation of SREBPs. Importantly, compound 49 displayed superior bioavailability (F = 65.1%) and obvious efficacy in the treatment of high fat diet induced obesity in vivo. Therefore, compound 49 is a promising candidate to develop new treatment of hyperlipidemia.

Abstract
Proprotein convertase subtilisin/kexin type 9 (PCSK9) modulators may attenuate PCSK9-induced low-density lipoprotein receptor (LDLR) degradation in lysosome and promote the clearance of circulating low-density lipoprotein cholesterol (LDL-C). A novel series of tetrahydroprotoberberine derivatives (THPBs) were designed, synthesized, and evaluated as PCSK9 modulators for the treatment of hyperlipidemia. Among them, eight compounds exhibited excellent activities in downregulating hepatic PCSK9 expression better than berberine in HepG2 cells. In addition, five compounds 15, 18, 22, (R)-22, and (S)-22 showed better performance in the low-density lipoprotein, labeled with 1,1′-dioctadecyl-3,3,3′,3′-tetramethyl-indocarbocyanine perchlorate (DiI-LDL) uptake assay, compared with berberine at the same concentration. Compound 22, selected for in vivo evaluation, demonstrated significant reductions of total cholesterol (TC) and LDL-C in hyperlipidemic hamsters with a good pharmacokinetic profile. Further exploring of the lipid-lowering mechanism showed that compound 22 promoted hepatic LDLR expression in a dose-dependent manner in HepG2 cells. Additional results of human ether-à-go-go related gene (hERG) inhibition assay indicated the potential druggability for compound 22, which is a promising lead compound for the development of PCSK9 modulator for the treatment of hyperlipidemia.
